DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0013] An automated liquid application system is proposed comprising a sprayer trolley that can either manually or automatedly move horizontally and vertically along the exterior of a building or large industrial surface, evenly spraying liquid on the wall. Embodiments of the system may comprise one or more different system designs for implementing automation or for suspending the sprayer trolley. Each design would be optimized for specific industrial exteriors and for specific liquid application.

[0014] FIG. 1 depicts a birds-eye perspective of an exemplary liquid application system with the ability to be controlled manually or automatedly. The liquid application system [100] is constructed of a sprayer trolley [105] moving horizontally along guiding cables [110a-b] held in a vertical position with suspension cables [130a-b], where the vertical position is adjusted using the cable motors [120a-b]. The sprayer trolley [105] is further supported by a horizontal support beam [115]. In some embodiments, the sprayer trolley [105] may be suspended on the guiding cables only [110a-b] or may be supported on a horizontal support beam [115] only. The horizontal support beam [115], guiding cables [110a-b], and sprayer trolley [105] system is connected to cable motors [120a-b] allowing automated adjustments to the system vertically up and down the suspension cables [135]. In some embodiments, the support structure [130] may be additionally constructed or alternatively constructed of rigid beams. As the sprayer trolley [105] moves horizontally along guiding cables [110a-b], liquid tubing [125] transports liquid from an exterior, remote source to the sprayer trolley [105], and then from the sprayer trolley [105] to be applied onto an exterior surface. In some embodiments, the liquid applied may be paint or primer. In some embodiments, the liquid applied may be water, with or without additional chemicals, used for pressurized cleaning of the exterior surface. The sprayer trolley [105] is powered by a power cable [135]. In some embodiments, the power cable [135] may be connected to an electrical grid or may be connected to a generator.

[0015] In some embodiments, the sprayer trolley [105] may not be configured with a power cable and, instead, may have a rechargeable inner power source. In some embodiments, the power cable [135] may convey logical steps, executable by a computer processor, such as a program. In some embodiments, the sprayer trolley [105] may have remote connection capabilities, such as Bluetooth or wireless internet connections, to convey programming or information. In some embodiments, the sprayer trolley [105] may be additionally configured with an exterior, pressurized liquid holding tank, connected to the sprayer trolley. The motorized and automated vertical and horizontal movement capabilities of the liquid application apparatus [100] advantageously allow the apparatus to be used in various locations and for diverse purposes.

[0016] FIG. 2 depicts an exemplary sprayer trolley internal configuration. The exemplary sprayer trolley [200] is constructed of a sprayer trolley housing [230] with an access point for a sprayer nozzle clamp [205] and guiding cables [210a-b]. The exemplary sprayer trolley [200] is configured to move laterally or horizontally along a guiding cable [210a-b] and the direction can be adjusted by activating either cable directional switch [215a-b].

[0017] FIG. 2, is additionally constructed of a sprayer [245] fixed to the sprayer trolley housing [230] with the sprayer connection mechanism [240], which is then adjusted with the sprayer nozzle clamp [205]. connected to liquid tubing [220], where the liquid tubing is tubing for the purpose of transporting liquids. In some embodiments, the liquid in the liquid tubing [220] may be paint or primer for application. In some embodiments, the liquid in the liquid tubing [220] may be water, either treated with chemicals or not. In some embodiments, the liquid tubing is connected to an exterior tank or holding cell containing the paint, primer, or a water solution. The sprayer [245] is activated by engaging or disengaging the sprayer trigger [250], automatedly or manually, with the sprayer trigger motor [255]. For example, the sprayer trigger [250] may be disengaged when areas that do not need liquid application or where liquid application may be harmful, are a part of the industrial surface. These areas may be windows, large open areas, or surfaces with an irregular shape, for example. The sprayer [245] of the sprayer trolley [200] may advantageously be any standard industry sprayer which also allows for the same sprayer trolley to be used for various applications.

[0018] The apparatus of FIG. 2, the sprayer trolley [200], is further constructed with a sprayer trigger motor [255], activated by the sprayer trolley power source [235], which is connected to an external power source through a power cable [225]. In another example, the apparatus in FIG. 2 may be constructed without a sprayer trolley power source [235] or power cable [225], and may instead be constructed with a rechargeable battery. In this example, a cable may carry logical steps in the form of code to the apparatus. In some embodiments, the apparatus in FIG. 2 may be constructed with a Bluetooth or wireless connection. The sprayer trolley [200] is configured for optimal flexibility for industry professionals and, therefore, can be used with various sprayers.

[0019] FIG. 3 depicts an alternative internal perspective of an exemplary sprayer trolley configuration moving along a support beam [315]. The sprayer trolley [300] is constructed of a sprayer trolley housing [305], a sprayer connection mechanism [330], and access ports for guiding cables [310a-b], a sprayer nozzle [335], and a sprayer nozzle clamp [325]. The sprayer trolley [300] may travel horizontally along various support structures, such as a support beam [315], using the guiding cable motor [340] to pull the sprayer trolley [300] either left or right along the guiding cable [310a-b], depending on whether the right or left cable directional switch [320a-b] is activated. The direction of the sprayer trolley [300] may be adjusted by activating one of the cable directional switches [320a-b] while deactivating the other. The sprayer trolley [300] is advantageously constructed with directional switches and motors to allow for maximum flexibility and efficiency.

[0020] The apparatus in FIG. 3, is additionally constructed with up to four sensors [345a-d]. In some embodiments, the sensors may be used to detect open spaces or windows. In some embodiments, the sensors may be used to detect changes in surface texture. In some embodiments, the sensors may be used to detect temperature changes. The sensors may all detect the same elements but they may also detect various elements. These sensors advantageously allow for the sprayer to automatedly start or stop when detecting an abnormal surface texture, for example. These embodiments have the benefit of creating a programmable sprayer trolley [300].

[0021] FIG. 4 depicts a view of an exemplary programmable remote control used to program or manually adjust the sprayer trolley system and apparatus from a remote location. The sprayer trolley remote control [400] is constructed predominantly of manual controls along the top row of control mechanisms and predominantly of automated controls along the bottom row of control mechanisms. The top row is configured to adjust the sprayer trolley vertically by activating or deactivating the cable motors with the manual trolley control (vertical) [435]; to activate or deactivate the cable motors with the cable motor system control [430]; to adjust the cable directional switches and guiding cable motor, and thereby control the horizontal directionality of the sprayer trolley with the manual trolley control (horizontal) [430]; and to engage the sprayer with the start [420] button. The bottom row is configured to set the sprayer trolley system to adjust vertically upwards or downwards with the automated vertical adjustment [405]; to set a distance for the sprayer trolley to travel horizontally with the automatic lateral distance control [410]; to set a speed for the sprayer trolley to travel at a set speed horizontally with the automatic speed control for lateral movement [410]; and to disengage the sprayer with the stop [415] button. This exemplary sprayer trolley remote control [400] advantageously allows for ease of use in rugged environments while providing a user with maximum flexibility to switch between manual and automated uses.

[0022] The method used by the liquid application system sets a moving speed horizontally and a horizontal distance. Once the distance is traveled, the cable motors drop the sprayer trolley a set distance to then travel horizontally at the set speed and distance, until the full industrial surface has been evenly applied with liquid.

[0023] Although various embodiments have been described with reference to the FIGs, other embodiments are possible. For example, an alternative embodiment may use an application on a computer instead of a remote control with remote connection capabilities. Those remote connection capabilities may include Bluetooth technology, wireless internet, or radio frequencies. For example, a remote may be constructed with only automated or manual controls allowed. In an alternative embodiment, an application on a mobile device or tablet may be used instead of a remote control.

[0024] An alternative embodiment may allow for a small, pressurized holding tank with the liquid to be applied attached to the sprayer trolley. An alternative embodiment may allow for various nozzles where different liquids may be applied subsequently. An alternative embodiment may allow for one nozzle applying liquid and a subsequent nozzle applying air to aid in drying a surface, housed in one sprayer trolley. An alternative embodiment may allow for more than one horizontal cable to be suspended at various vertical heights, each with a sprayer trolley, applying liquids horizontally simultaneously. An alternative embodiment may allow for more than one sprayer trolley applying liquid simultaneously along a single guiding cable and/or support beam.

[0025] For example, a liquid application system may be constructed with a trolley suspended vertically on a cable and then moving horizontally with cable motors moving the liquid application system first vertically, and then horizontally. In this embodiment, the method would reflect that change for first vertical movement and then horizontal movement.

[0026] For example, a liquid application system may be constructed for use with a building exterior. In an alternative embodiment, a liquid application system may be constructed for use with an airplane exterior. The liquid application system is best suited for large, industrial, exterior surfaces. The liquid in the liquid application system, in another example, may be an aqueous solution or may be pure water. In another example, the liquid in the liquid application system may be paint or primer.

[0027] A number of implementations have been described. Nevertheless, it will be understood that various modification may be made. For example, advantageous results may be achieved if the steps of the disclosed techniques were performed in a different sequence, or if components of the disclosed systems were combined in a different manner, or if the components were supplemented with other components. Accordingly, other implementations are contemplated.
